FASTENING FOR BAG OR POCKET-BOOK FRAMES.

SPECIFICATION forming part of Letters Patent No. 363,042, dated May 17, 1887.

Application filed March 1, 1887. Serial No. 229,298. (No model.)

To all whom it may concern:

Be it known that I, CHARLES BI.UsT,of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Fastenings for Bag or Pocket- Book Fra1nes,of which the following is a specification.

My invention relates to the class of fastenings for securing together the two hinged portions of a bag or pocket-book frame, which comprise a rotary catch turning upon a post projecting from one frame portion and aspring for causing the catch to engage automatically with the locking-tooth on the other frame pen I 5 tion, the catch and post being provided with bearings, one of which is inclined to produce the axial movement of the catch out of engagement with the lockingtooth when the catch is turned upon the post.

The object of my invention is to provide a catch of the kind above described which may be operated to release the two frame portions when it is turned in either direction on its post, and also to secure the arrangement of such catch centrally between the two frame portions; and these advantages are secured by novel combinations of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings,Figure l is a sectional View of two frame portions of a bag in a plane transverse to their length. Fig. 2 is a side view of one of the frame portions and the catch. Fig. 3 is an axial section of a catch alone removed from the post on which it turns. Fig. 4 is a perspective view of a bearing-piece which is provided on the post; and Fig. 5 is a sectional view corresponding to Fig. 1, showing a slight modification of myinvention.

Similar letters of reference designate corresponding parts in all the figures.

A ,A designate the two frame portions, which may be of hollow or tubular construction, made of sheet metal bent into proper shape, and which are hinged together at I) in a well-known manner.

Upon one of the frame portions, A, I have represented a locking tooth or projection, b, and upon the other frame portion I have rep- 5o resented a post, b on which is journaled or fitted a rotary catch, B. This catch is recessed or rabbctcd at the bottom, as shown at b so that when journalcd upon the post I)" it is adapted to embrace or engage the lockingtooth b, as shown in Fig. 1. The post If, I prefer to form with an offset, b", or, in other words, make it in the form of a crank, so that the portion of the post on which the catch B isjournalcd' will be located centrally between the two frame portions A A, or, in other words, so that the axis of the catch 13 will fall between the two frame portions.

In order to effect the axial movement ofthe catch B when turned on the post b", I provide two bearings, one on the catch and the other upon the post, and I form one of those bearings with reverse inclines, so that when the catch is turned in either direction it will be caused to move axially outward from the frame in order to disengage it from the locking tooth Z).

In the example of my invention shown in Figs. 1 to 4, inclusive, the bearing which is upon the catch B consists simply of a collar,

0, soldered or otherwise secured in the catch,

as best shown in Fig. 3, and having a down- 31 wardlyproieeling tooth, c, of V-shaped form, and the bearing upon the post consists of a collar, 0", best shown in Fig. 4, and having V-shaped notches c, in which the tooth c bears. The sides of the tooth 0 form reverse 8o inclines in the bearing of the catch, and the sides of the notches 0 form corresponding reverse inclines in the bearing on the post, and consequently, when the catch B is turned it will be moved axially away from the frame portions sufficiently to disengage it from the locking-tooth b. A spring, d, surrounds the post b within the catch B, and by bearing at one end against the collar 0 in the catch and at the other end againstawasher,d,secured on the end of the post, the spring exerts a resistance to the movement of the catch in the axial direction necessary to effect the disengagement of thecatch from the locking-tooth Z).

I have shown the outer end of the tooth b as slightly inclined, and when the two frame portions A A are pressed together this tooth will raise the catch and effect the automatic engagement of the catch with the tooth, and the catch may be disengaged from the tooth b by a rotary movement in either direction or by simply sliding it outward upon the post,

the catch in either case being moved axially outward against the force'of the spring d.

In the example of my invention shown in Fig. 5 the construction is the same as that above described, save that instead of the bearing on the eatch'being formed by a tooth, c,as in the previous figures, it is formed by a pin, a, 'which is inserted transversely to the axis of the post 6 and which rides upon the bearing a 0 provided upon the post.

What I claim as my inventiomand desire to secure by Letters Patent, is

l. The combination, with the two hinged portions of a pocket-book or bag frame, of a post projecting from one and a locking-tooth projecting from the other of the frame portions, a rotary catch on the post, bearings on 20 the post and catch one of which has reversed inclines to effect the axial movement of the catch when turned in either direction on the post, and a spring acting on the catch to move it axially into engagement with the lockingtooth, substantially as herein described.

' 2. The combination, with the two frame portions AA,respectively having thelockingtoot-h b and the cranked or offset post bflof the rotary catch 13, journaled on the post, the spring d, for forcing the catch into engagement with the tooth b, and bearings on the post and catch, one of which is inclined to effect the axial movement of the catch when turned on the post, substantially as herein described.
